Exhaust question

[SnucksOG]

Hey, I'm about to put my germinated seeds in dirt and I was wondering. Should I have my exhuast fan going as soon as I put them in the dirt or shit I wait? Thanks in advance.

I don't put my extraction on until I use my hps. While using cfl on young seedlings I only have a small fan blowing across them.

Depends on temp and how secure you are for smells.

I don't have cfls I am using my CMH light.

Unless it's really hot you have no need for it yet.

All depends on the heat in the tent then. You won't need to worry about smells from seedlings. As long as you have air movement and it don't get too hot there's no need for extraction yet

What would be too hot cause... I have gotten temps as high as 90... With my 6inch exhuast going with two passive intakes. I have a 4inch active air intake fan on the way. I have been fighting the temp all day trying to find a way to dial it in.,

What is a good cheap temp controller. Also .y humidity will not go past 20-30 percent. What should o get to help with that

I use these all the time about 100 bucks down here in oz, they do what there supposed to do, they work. mine are in a clone cupboard with big door, , high humidity but still gets down so I have a big tub of water in there that brings it up some, I like about 70 80 c, but 50 60 sometimes. small tent fan in there also.
